What if the seller refuses to take the car back?

Park the RV in a high traffic area, with permission of the landlord, with huge signs that read: I bought this lemon at such and such dealership. They hate negative publicity and will usually do something just to avoid further negative publicity. Call the dealership and tell them you plan to leave the vehicle with the signs on it until they do something or go out of business. Try to park the thing as close to the dealership as possible so that future potential customers going to do business there will see the lemon advertisement. ANSWER lET THE BUYER BEWARE. if you bought it from another individual or used car dealer, you should have the car checked by a mechanic or take a mechanically inclined person with you. if you feel you bought a lemon, there are consumer agencies you can contact like the better business bureau, local tv stations, your local consumer affairs office or court.
